When you spend the kind of time that I do browsing research findings, you inevitably end up on weird sites with weird stuff at times.
The site Giant Microbes takes first prize in offering weird gifts for biology nerds (who else would be interested in a stuffed animal representing the common cold, a bed bug or mange?!). Some of the microbes are animated for our entertainment. Select "White Blood Cell" (a "leukocyte" in Latin) and check out the little fellow doing the happy dance.
Okay, enough on this silly site. You'll know you have too much time on your hands (or that you are a closet biology nerd with a warped sense of humor) if you explore the Giant Microbes site in any detail. If you buy anything on this site, you'll have to let me know what you bought and why. :-)
